Etiology: Band keratopathy derives its name from the distinctive appearance of calcium deposition in a band across the central cornea. Band keratopathy can occur from a variety of causes, both systemic and local. Bank keratopathy is associated with chronic corneal edema (perhaps the most common treatable cause accounting for over 1/4 of cases in one series), phthisis bulbi, chronic iridocyclitis, severe glaucoma, hyperparathyroidism, vitamin D excess, sarcoidosis or renal disease. The latter 4 are related to abnormal calcium metabolism. Severe dry eye may also precede band keratopathy. Herpes keratitis may predispose to band keratopathy. The use of phosphate salts in steroid preparations may precipitate calcium in patients with epithelial defects ...

Methods: Tissue sections of formalin-fixed, paraffin-embedded corneal specimens (keratoconus, pseudophakic bullous keratopathy, epithelial downgrowth, failed corneal grafts with retrocorneal fibrous membranes, and postmortem control corneas) were immunostained with a panel of corneal epithelial and endothelial markers (EMA, KAE 1/3, CAM5.2, Factor VIII, CD-34, CD-31) and with Vimentin using the Strept-Avidin technique (Dako). Results: Corneal endothelium is immunonegative for endothelial cell markers (CD-34,CD-31, and Factor VIII) and displays immunopositivity for epithelial markers (KAE 1/3, CAM 5.2). ...

Case Report DOI:10.14744/bej.2019.79553 Beyoglu Eye J 2019; 4(2): 126-129 Manual Intracorneal Silicone Oil Insertion for Symptomatic Treatment of Bullous Keratopathy in a Patient with Corneal Scarring Selim Genc, Semih Cakmak, Yusuf Yildirim Department of Ophthalmology, University of Health Sciences, Beyoglu Eye Training and Research Hospital, Istanbul, Turkey Abstract Bullous keratopathy is a result of endothelial loss and the failure of the remaining corneal epithelium to pump leaking water molecules away from the corneal tissue, causing overhydration. In eyes with good visual potential, keratoplasty is the primary treatment. There are also several other approaches to provide temporary improvement until a permanent solution with keratoplasty can be achieved. These alternatives include hypertonic topical sodium chloride (5%) drops, bandage contact lenses, anterior stromal puncture, phototherapeutic keratectomy, amniotic membrane transplantation, conjunctival flaps, and collagen crosslinking. ...

TY - JOUR. T1 - Autologous cultivated limbal stem cell transplantation after failed previous limbal graft. AU - Knutsson, KA. AU - Matuska, S. AU - Rama, P. PY - 2017. Y1 - 2017. N2 - Purpose: To describe a case of unilateral limbal stem cell deficiency (LSCD) with previously failed autologous graft, resolved by ocular surface reconstruction using cultured autologous limbal stem cells from the contralateral eye. Case report: A 35-year-old patient presented to our clinic with LSCD due to a unilateral alkali burn. The patient had received a previous limbal graft from the contralateral eye that had failed to impede corneal conjunctivalization. We decided to repeat limbal stem cell transplantation using an ex vivo cultivation procedure to reduce the risk of tissue harvesting on the healthy fellow eye. A small limbal biopsy (1.5 × 1.5 mm) near the previously excised limbus was performed. Stem cells were then isolated and cultured on fibrin and a 3T3 feeder cell layer using a standard protocol. Four ...

PURPOSE: We report our experience with the use of maternally derived serum eye drops as adjunctive treatment in the management of pediatric persistent corneal epithelial defects. METHODS: Five eyes of 4 patients were identified in a retrospective review of pediatric patients with persistent corneal epithelial defects who received maternal serum drops. Diagnoses associated with the defects comprised pontine tegmental cap dysplasia with bilateral cranial nerve V1, V2, V3, and VII palsies; pontine tegmental cap dysplasia with left cranial nerve V1, VII, and VIII palsies; traumatic left cranial nerve II, V1, V2, and VI palsies due to a basilar skull fracture; and Stevens-Johnson syndrome with ocular involvement ...

Preoperative and postoperative endothelial cell morphology was examined in three types of patients participating in a randomised, controlled trial of cataract surgery. The first sustained modest endothelial cell loss and served as controls, the second and third sustained high cell loss, but only the latter progressed to bullous keratopathy. The technique of examining endothelial cell morphology is described and its validity assessed. Measures of cell area, number of sides, side length, and variation in cell size and cell shape were utilised. No significant differences were found between the three groups by any of the preoperative morphological measures. Furthermore, postoperative values of variation in cell shape and cell size did not differ significantly between the groups. No evidence was found in our patients to support the hypothesis that eyes at particular risk of developing bullous keratopathy may be differentiated on the basis of their preoperative or early postoperative endothelial cell ...

Aims: To describe the long-term risk of bullous keratopathy following argon laser iridotomy (ALI) in Japan and to compare it with other centres in the world.. Methods: We retrospectively reviewed the case records of all patients with ALI-induced bullous keratopathy that underwent penetrating keratoplasty at Kyoto Prefectural University of Medicine (KPUM) from January 2001 to December 2004. The results were compared with the other representative centres in Singapore and the UK.. Results: Thirty-nine eyes of 33 patients were included in the study. The mean age of patients was 73.3±6.9 years (range, 58 to 87 years). Patients developed bullous keratopathy at a mean duration of 6.9±4.9 years (range, 0.2 to 16 years) after the laser iridotomy procedure. The majority of eyes that developed bullous keratopathy (59.0%) occurred following prophylactic ALI. KPUM had the highest percentage of ALI-induced bullous keratopathy cases that underwent penetrating keratoplasties, as compared with other centres in ...

Abstract Objective: A population of stem cells (SCs) is responsible for maintenance and repair of the ocular surface. These stem cells can become deficient as a result of various diseases affecting the ocular surface. Depending on the extent of damage, the clinical features can vary from mild discomfort to substantial pain and/or blindness. The growing field of tissue engineering and advances in stem cell research offer promising new alternatives for these disorders. This student thesis will provide an overview of the human ocular surface (cornea, limbus, and conjunctiva), ocular surface stem cell deficiency, and treatment possibilities. Methods: This student thesis is based on a number of review articles and original articles on PubMed using the search words limbal, limbal stem cell deficiency, conjunctival and/or ocular surface reconstruction. Only papers written in English were considered. Findings: There are different possible methods for treating ocular surface stem cell deficiency by ...

Aniridia is a congenital autosomal dominant, bilateral, panocular condition, caused by haploinsufficiency of the Pax6 transcription factor. Aniridia-related keratopathy (ARK) significantly affects vision and quality of life in these patients. ARK is a chronic progressive keratopathy comprising limbal stem cell deficiency associated with impaired epithelial cell adhesion, corneal conjunctivalization, epithelial erosions and corneal vascular pannus that typically only appear after childhood.. The aims were i) to evaluate the structural changes and ii) cell signaling pathways, including the Notch1, Sonic Hedgehog (SHH), mTOR and Wnt/beta-catenin cell signaling pathways in naïve and surgically treated corneas of aniridia cases with advanced ARK and comparing with normal human adult and fetal corneas and iii) to develop a corneal cell culture model of aniridia.. Naïve ARK corneas removed at the time of the first transplantation and ARK corneal buttons removed after a failed keratolimbal allograft ...

Band keratopathy is characterized by the appearance of a band across the central cornea, formed by the precipitation of calcium salts on the corneal surface (directly under the epithelium). This form of corneal degeneration can result from a variety of causes, either systemic or local, with visual acuity decreasing in proportion to the densit...

Corneal transplant surgery is the most commonly performed of all transplant operations, with approximately 45,000 corneal transplant procedures being performed in the Unites States each year. The indications for corneal transplant surgery have changed through the years. Pseudophakic bullous keratopathy and aphakic bullous keratopathy (corneal edema secondary to cataract surgery) accounted for 80% of corneal transplants in the 1980s. However, with the improvement of cataract surgery techniques, conditions such as Fuchs Dystrophy, Keratoconus, and other corneal dystrophies are now more commonly transplanted.. In 1933, corneal transplants were performed using two razor blades to make a square graft. Patients were hospitalized for two weeks with sand bags on either side of their head to prevent undesirable movement and possible leakage from the wound sites. Since then, there have been major advances in surgical technique including the introduction of the operating microscope (1970s) and better ...

Bullous keratopathy is a condition where corneal endothelial cells, which do not normally proliferate in vivo, are extensively impaired by trauma, disease, surgery or the like and do not longer maintain the transparency of the cornea, leading to edema and turbidity. Kyoto Prefectural University of Medicine and Doshisha University jointly expanded corneal endothelial cells derived from donors and injected them into the anterior chamber of patients with keratopathy. 11 cases of a clinical study now confirmed effectiveness and safety of this treatment.. AMED news release, March 15, 2018. ...

Purpose: To evaluate the preoperative indications, postoperative complications, retention rate and surgical outcomes of patients with Boston Type I (formerly Dohlman type I) Keratoprosthesis in an international center.. Methods: An observational and retrospective study was performed with review of the medical records of patients who underwent Boston Type 1 Keratoprosthesis (KPro) implantation at Instituto de Oftalmología Conde de Valenciana (an ophthalmologic reference center) in Mexico City, Mexico. The variables analyzed included surgical indication, initial and final visual acuity, previous keratoplasties, postoperative complications and retention rate.. Results: 22 eyes of 21 patients with a median age of 49.5 years (range 24 - 90 years), median follow-up after keratoprostheses of 14 months (range 3 to 124 months). Preoperative visual acuity was worst than 20/100 in all cases. Indications for surgery included: corneal dystrophies in 4 patients (19.0%), ocular burns (2 patients, 9.5%), ...

The Table summarizes the patients demographics, ocular comorbidity, concomitant treatment, and clinical manifestations including symptoms and signs at the presentation. Conjunctival inflammation was graded according to the conjunctival injection as none (0), mild (1), moderate (2), and severe (3). The corneal surface integrity was scored as clear (0), scattered superficial punctuate keratitis (SPK; 1+), moderate SPK (2+), and diffuse SPK with or without corneal epithelial defects (3+). The tear function was assessed by the fluorescein clearance test as reported28 using the Schirmer paper strip following topical application of 5 μL of Fluroress (Akorn Inc., Abita Springs, LA). The diagnosis of dry eye disease (DED) was based on the wetting length of less than 3 mm at the 10th and 20th minute. For Case #2 who presented with epithelial basement membrane dystrophy (EBMD), the diagnosis was confirmed by observing corneal epithelial wrinkles or breaks by the screwdriver test, which applies a dry ...

Recurrent Corneal Erosion (RCE) syndrome is a common, recurrent condition caused by abnormal epithelial adhesion to the underlying basal lamina. The spontaneous breakdown of the corneal epithelium can lead to the sudden onset of ocular pain, blurred vision, tearing, and photophobia, typically upon awakening.[1][2][3]

Keratoconus (Online Mendelian Inheritance of Man [MIM] 148300) is a common bilateral ocular disease characterized by progressive corneal thinning and ectasia. The progressive corneal thinning (mean central corneal thickness [CCT]) results in myopia and corneal astigmatism. Genome-wide association studies (GWAS) in different populations have showed that common noncoding single nucleotide polymorphisms (SNPs) of zinc finger 469 (ZNF469 [MIM 612078]) are strongly associated with CCT. 1,2 Moreover homozygous mutations in ZNF469 lead to brittle cornea syndrome type 1 (BCS1 [MIM 229200]), a rare autosomal recessive connective tissue disease associated with abnormal thin corneas. 3 Since homozygous ZNF469 mutations result in a corneal thinning disorder, and since common SNPs 100-kb upstream of ZNF469 are strongly associated with CCT, Vincent et al. 4 hypothesized that heterozygous variants in ZNF469 might predispose to the development of isolated keratoconus. Therefore, the coding regions of ZNF469 ...

The results from this research may open the door to future therapeutics for a myriad of corneal disorders. It is essential to know the biochemical composition of normal healthy corneas in the effort to understand the molecular mechanisms behind corneal disorders, emphasizes Dr. Enghild. By comparative proteomic studies of diseased and normal corneas we can identify differences in the expression profiles that may suggest avenues for therapeutic interventions. Because the cornea is so accessible, the potential for developing effective drugs for the treatment of corneal diseases is good. Furthermore, the work is likely to improve the clinical classifications of corneal diseases. Identification of the protein profile of the normal human cornea may also be very useful in the effort toward generating artificial corneas for transplantation ...

Results: The mice treated with limbal fibroblast conditioned media demonstrated substantial growth ...

Ocular surface is composed of corneal and conjunctival epithelial cells. Normal cornea is essential for normal vision. Defects in renewal and repair of ocular surface as a result of limbal stem cell deficiency are now known to cause varying ocular surface morbidity including persistent photophobia, repeated and persistent surface breakdown and overt conjunctivalisation of the cornea. Restoring ocular health in these eyes has traditionally been frustrating. Ex vivo cultured limbal epithelial stem cells have been used successfully to treat limbal stem cell deficiency. Ex-vivo limbal stem cell allograft transplantation is achieved by harvesting limbal corneal tissue from donor eyes (either matched living relatives or cadaveric donors). The donor stem cells are obtained by excising a small area of the conjunctiva at the limbus and are a minor procedure. The tissue so obtained is then grown in tissue culture and once the cells have multiplied sufficiently, small sheets are transplanted on to the ...

Background & Aims: This study was carried out to determine the leading indications for corneal transplantation in Kerman province. Methods: Medical records of 186 patients underwent corneal transplantation during 3 years (2004-2006) in Shafa Medical Center were evaluated retrospectively. The initial diagnosis and causes of corneal grafting were recorded. Infectious keratitis (Bacterial, Fungal, and acanthamoeba keratitis), corneal opacity and scarring, keratoconus, bullous keratopathy, regrafting, corneal dystrophy and degeneration, herpes simplex keratopathy (active keratitis), etc. were considered as indications of corneal transplantation. Results: A total of 186 patients (110 males, 76 females) were included in the study. Mean age of patients was 47.7± 24.3 years (6-85). The leading indications of grafting was corneal opacity (32.3%) followed by keratoconus (22.6%), bacterial keratitis (15.6%), aphakic bullous keratopathy (6.7%), pseudophakic bullous keratopathy (6.5%), regrafting (4.8%), herpes

Overview Iridocorneal Endothelial Syndrome (ICE) is a grouping of three closely linked conditions: Iris Nevus (or Cogan-Reese Syndrome), Chandlers Syndrome and Essential Progressive Iris Syndrome. There are three main features of ICE: visible changes of the iris, swelling of the cornea and the development of glaucoma, which can cause severe vision loss. Warning Signs & Symptoms ICE causes corneal swelling, distortion of the iris and variable degrees of distortion of the pupil, the adjustable opening at the center of the iris that allows varying amounts of light to enter the eye. This cell movement also plugs the fluid outflow channels of the eye, causing glaucoma. Treatment/Procedures While it is not yet known how to keep ICE syndrome from progressing, the glaucoma associated with the disease can be treated with medication, and a corneal transplant can treat the corneal swelling.. Prevention The cause and prevention of this disease is unknown. Rehabilitation If a corneal transplant is required, ...

Calcific band keratopathy (CBK) is a degenerative condition resulting in the deposition of calcium salts in the superficial layers of the cornea and causing significant visual disturbance and pain of the affected eye. The amount of CBK precipitates recovered from the affected eye is very small rendering a great challenge in development of an effective and non-invasive treatment for this condition. This provides an impetus to study the possible chemical factors that may contribute to the development of CBK in an effort to develop a more efficient and un-intrusive treatment for this condition. To this end, we have developed an in-vitro model system resembling band keratopathys chemical composition and morphology thus providing insight to the mechanism of formation and allowing for mass production of the material furthering the advances of therapeutic targeting CBK. Our study is the fIrst to demonstrate that low molecular silicon can assist in the formation of CBK. Given the predominance of ...

PURPOSE: To determine the epithelial phenotype in patients with a limbal stem cell deficiency (LSCD) after ocular surface reconstruction with autologous cultured stem cells. To correlate the epithelial phenotype with the clinical outcome.. METHODS: Six eyes affected by LSCD, verified and graded by impression cytology, were treated with an autologous fibrin-cultured limbal stem cell graft. The clinical outcome was defined as a success or a failure, depending on ocular surface stability. To improve their visual function, 4 patients underwent lamellar or penetrating keratoplasty after the stem cell graft. The phenotype of the regenerated corneal epithelium was determined by immunofluorescence of the corneal button to detect CK12, CK3, CK19, and Muc1 as corneal and conjunctival markers.. RESULTS: After a mean follow-up of 24 months, 5 cases were defined as successes; 1 case presented an epithelial defect 4 months after grafting and was defined as a failure. Immunofluorescence performed on 4 ...

In corneal transplant, also known as keratoplasty, a patients damaged corneais replaced by the cornea from the eye of a human cadaver. This is the single most common type of human transplant surgery and has the highest success rate. Eye banks acquire and store eyes from donor individuals largely to supplythe need for transplant corneas.. Corneal transplant is used when vision is lost in an eye because the cornea has been damaged by disease or traumatic injury. Some of the disease conditions that might require corneal transplant include the bulging outward of the cornea (keratoconus), a malfunction of the inner layer of the cornea (Fuchs dystrophy), and painful swelling of the cornea (pseudophakic bullous keratopathy). Some of these conditions cause cloudiness of the cornea; others alter itsnatural curvature, which can also reduce the quality of vision.. Injury to the cornea can occur because of chemical burns, mechanical trauma,or infection by viruses, bacteria, fungi, or protozoa. Herpes ...

It has been increasingly recognized that the corneal nerves play a key role in maintaining the anatomical integrity and functions of the cornea. Corneal nerve damage can lead to transient or chronic neurotrophic deficits with a decrease in the viability, metabolism, and rate of mitosis of the epithelial cells. This may result in epithelial intracellular swelling, loss of microvilli, and abnormal production of the basal lamina. As a consequence, symptoms of dry eye, corneal damage and infection develop known as neurotrophic keratopathy (NK) [1],[2].. The vast majority of the corneal nerves are derived from the ophthalmic branch of the trigeminal nerve [4]. Therefore, NK can be induced by any damage to the corneal sensory nerve pathways [1],[2]. The most common cause of NK is the peripheral corneal sensory nerve injury induced by viral infection, refractive surgery, chemical or thermal burns, ocular medication, and wearing contact lenses. Moreover, NK may develop from the damage of the ophthalmic ...

Our purpose was to evaluate the diagnostic value of three-dimensional (3 D) CT surface reconstruction in spinal fractures in comparison with axial and reformatted images. A total of 50 patients with different CT-proven spinal fractures were analysed retrospectively. Based on axial scans and reformatted images, the spinal fractures were classified according to several classifications as Magerl for the thoraco-lumbar and lower cervical spine by one radiologist. Another radiologist performed 3 D CT surface reconstructions with the aim of characterizing the different types of spinal fractures. A third radiologist classified the 3 D CT surface reconstruction according to the Magerl classification. The results of the blinded reading process were compared. It was checked to see in which type and subgroup 3 D surface reconstructions were helpful. Readers one and two obtained the same results in the classification. The 3 D surface reconstruction did not yield any additional diagnostic information concerning type

Purpose: To evaluate the anatomic stability of an implanted Boston Type I Keratoprosthesis (KPro)-donor cornea interface, and assess the presence or absence of a potential space (gap) between the KPro front plate and donor cornea using anterior segment optical coherence tomography (AS- OCT). The presence of a gap would raise concerns of a possible pathway for the exchange of fluid between the ocular surface and the anterior chamber.. Methods: Fourteen eyes implanted with a Boston Type I KPro were studied by the non-contact technique of AS-OCT (AC Cornea OCT prototype, OTI, Canada). All the KPro devices had been implanted at least 4 weeks prior to the study (range: 1 to 22 months). Seven eyes had aphakic Kpros and the other 7 had pseudophakic implants. Anesthetized eyes were imaged before and during pressure application using sterile cotton tip applicators. Pressure was applied for 10 seconds just outside the temporal limbal area. Images were analyzed for any possible changes in the KPro-donor ...

Descemets membrane detachment and posterior wound gape, when they occur, develop very early after cataract surgery and decrease thereafter, while the incidence of posterior wound retraction emerges more slowly but is present in most eyes by 3 years postoperatively.

Cornea related injuries and diseases could be: cornea guttata, corneal dystrophy, corneal ulcer, keratoconus, corneal abrasion. All of these can lead to a loss of corneal transparency.. In these cases, the most common treatment consists in a corneal transplant, that makes it possible to see well again. If the disease is catched early, it is even possible to avoid the transplant altogether with a medical therapy.. If transplant fails, you can resort to artificial cornea, via the Boston Keratoprosthesis: the artificial cornea can give a new hope to many patients.. Cornea shields the inside of the eye just like the glass of a watch. It is composed of several layers; from the outside, there are, in order:. ...

Amniotic membrane, or amnion, is the innermost layer of the placenta and consists of a thick basement membrane and an avascular stromal matrix. Amniotic membrane transplantation has been used as a graft or as a dressing in different surgical subspecialties. In the field of ophthalmology, it is used broadly 1) to reconstruct the ocular surface after various procedures; 2) as a graft for ocular surface melts; and 3) as a bandage to promote healing in cases of persistent epithelial defects or ocular surface inflammation. All of these indications make use of amniotic membranes ability to promote healing.[1]

Due to its noninvasive accessibility and clarity, cornea serves an ideal target for evaluating the efficacy of various treatments against corneal disorders. A multitude of potential gene therapies based on different genes and strategies have been tried in the context of corneal diseases, including corneal NV. For example, various viral-mediated gene delivery systems have been proposed to produce expression of the desired genes with varying expression levels and duration [32-34]. In the case of gene therapy for corneal NV, as in many other situations, it is well recognized that targeting a single gene often fails to ensure the theoretically predicted efficacy [23,35-37]. We therefore investigated the possibility of better management of corneal NV by combining different anti-angiogenic factors in the present study. We showed that the combination of two or three genes exhibited additive effects over a single gene in inhibiting HUVEC proliferation in vitro (Figure 1A). This additive effect, however, ...

This video shows a cornea with amiodarone verticillata deposits. You can see these as a whorl pattern - the entity is also called whorl keratopathy or hurricane keratopathy. These deposits are benign, difficult to see, and rarely (if ever) have any visual significance.. Drugs that can cause this pattern: CACTI Mneumonic: chloroquine, amiodarone, chlorpromazine, tamoxifen, indomethacin.. In addition, you can presumably get a similar pattern with amodiaquine, meperidine, and with Fabrys disease.. ...

The human corneal endothelium regulates the cornea transparency. Its cells, that cannot regenerate after birth, form a tesselated mosaic with almost perfect hexagonal cells during childhood, becoming progressively bigger and less ordered during aging. This study included 50 patients (in 10 decades groups) and 10 specular microscopy observations per patient. Five different criteria were measured on the manually segmented cells: area and perimeter of the cells as well as reduced Minkowski functionals. All these criteria were used to assess the probability of age group membership. We demonstrated that the age evaluation is near the reality, although a high variability was observed for patients between 30 and 70 years old ...

The anterior axial CLMI calculated from the Keratron data was significantly higher than CLMI for the Galilei (p = 0.0443) or Pentacam (p , 0.0004) with keratoconus, 12.23 compared with 11.20 and 11.00 diopters, respectively. Kmax was also significantly higher in the Keratron than the Galilei (p = 0.0063) or the Pentacam (p , 0.0002). Galilei and Pentacam were not significantly different from each other in either CLMI (p = 0.6287) or Kmax (p = 0.2115). The anterior CLMI values for the postrefractive surgery ectasia eyes were not significantly different between devices. Posterior CLMI values were calculated from the Galilei and Pentacam data and were −2.60 and −2.46 diopters (p = 0.1173) for keratoconus and −2.66 and −3.04 diopters (p = 0.2242) for postrefractive surgery ectasia. ...

Corneal transplant surgeries in young patients resulted in improved vision and thereby a better living, says a study. Success rates of corneal transplants in kids was also high.

BACKGROUND/AIM: Keratoconus (KC) is a ectatic corneal disorder with marked progression during childhood and puberty that may lead to severe visual loss. In addition to KC prevalence, estimate shows major geographical variations; recent studies using Scheimpflug technology are in contrast to the 1980s and 1990s literature. The present study aims to determine the prevalence of KC in paediatric patients in Riyadh, Saudi Arabia (KSA). METHODS: This prospective, cross-sectional, observational, multicentre study collected data from paediatric patients from 6 years and 21 years of age who were seen at multiple non-ophthalmic emergency departments within KSA ...

Well, it appears the saga of my cat-and-book-induced eye injury is not quite over, after all. As reported here earlier, the injury itself seemed to heal up nicely in a few days, but recently Ive started noticing that when I look at a bright light against a dark background, Im getting some mildly disturbing blurring effects, and, in certain circumstances, a sort of faint second image of the bright object, just with that one eye. So, like the conscientious patient I occasionally am, I went in to see the optometrist. He didnt confirm any of my paranoid hypochondriac worries, thank goodness. (Yes, I will admit that part of my brain kept going, Aaargh, Im developing a cataract! Maybe its glaucoma! Help, my retina is detaching!) He said the cornea looks nice and healed up, but there is some degradation in the epithelium and that I am at risk for something called recurrent corneal erosion. Which means, basically, that your eyeball sticks to your eyelid, especially when youre asleep, and then ...

Until their disease starts to quiet down. Could be a little challenging. I was trying to make a few incisions here to see if there was another layer interface. But I dont think there is. What we dont want to do is we do not want to perforate. Because that would require tissue. So, I think the emphasis on diseases like Stevens-Johnson need to be in the acute care of these patients. And that really means the hospitals have to have good communication with the ophthalmologist so that there can be aggressive in that early acute phase. When there is actually something we can do for these patients and not in the end stage where theres very little we can offer these patients ...
