Macula Lutea
An oval area in the retina, 3 to 5 mm in diameter, usually located temporal to the posterior pole of the eye and slightly below the level of the optic disk. It is characterized by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its center, and provides the best phototropic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid. (From Cline et al., Dictionary of Visual Science, 4th ed)
Corpus Luteum
Acoustic Maculae
Juxtaglomerular Apparatus
A complex of cells consisting of juxtaglomerular cells, extraglomerular mesangium lacis cells, the macula densa of the distal convoluted tubule, and granular epithelial peripolar cells. Juxtaglomerular cells are modified SMOOTH MUSCLE CELLS found in the walls of afferent glomerular arterioles and sometimes the efferent arterioles. Extraglomerular mesangium lacis cells are located in the angle between the afferent and efferent glomerular arterioles. Granular epithelial peripolar cells are located at the angle of reflection of the parietal to visceral angle of the renal corpuscle.

Progesterone
The major progestational steroid that is secreted primarily by the CORPUS LUTEUM and the PLACENTA. Progesterone acts on the UTERUS, the MAMMARY GLANDS and the BRAIN. It is required in EMBRYO IMPLANTATION; PREGNANCY maintenance, and the development of mammary tissue for MILK production. Progesterone, converted from PREGNENOLONE, also serves as an intermediate in the biosynthesis of GONADAL STEROID HORMONES and adrenal CORTICOSTEROIDS.
Luteolysis
Estrus
Ovary
The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.
Corpus Luteum Maintenance
Process of maintaining the functions of CORPORA LUTEA, specifically PROGESTERONE production which is regulated primarily by pituitary LUTEINIZING HORMONE in cycling females, and by PLACENTAL HORMONES in pregnant females. The ability to maintain luteal functions is important in PREGNANCY MAINTENANCE.

Luteal Cells
Saccule and Utricle
Two membranous sacs within the vestibular labyrinth of the INNER EAR. The saccule communicates with COCHLEAR DUCT through the ductus reuniens, and communicates with utricle through the utriculosaccular duct from which the ENDOLYMPHATIC DUCT arises. The utricle and saccule have sensory areas (acoustic maculae) which are innervated by the VESTIBULAR NERVE.
Ovarian Follicle
An OOCYTE-containing structure in the cortex of the OVARY. The oocyte is enclosed by a layer of GRANULOSA CELLS providing a nourishing microenvironment (FOLLICULAR FLUID). The number and size of follicles vary depending on the age and reproductive state of the female. The growing follicles are divided into five stages: primary, secondary, tertiary, Graafian, and atretic. Follicular growth and steroidogenesis depend on the presence of GONADOTROPINS.

Bruch Membrane
The inner layer of CHOROID, also called the lamina basalis choroideae, located adjacent to the RETINAL PIGMENT EPITHELIUM; (RPE) of the EYE. It is a membrane composed of the basement membranes of the choriocapillaris ENDOTHELIUM and that of the RPE. The membrane stops at the OPTIC NERVE, as does the RPE.
Chorionic Gonadotropin
A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).
Pregnancy
Luteinizing Hormone
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.
Visual Acuity
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.

Gonadotropins, Equine
Gonadotropins secreted by the pituitary or the placenta in horses. This term generally refers to the gonadotropins found in the pregnant mare serum, a rich source of equine CHORIONIC GONADOTROPIN; LUTEINIZING HORMONE; and FOLLICLE STIMULATING HORMONE. Unlike that in humans, the equine LUTEINIZING HORMONE, BETA SUBUNIT is identical to the equine choronic gonadotropin, beta. Equine gonadotropins prepared from pregnant mare serum are used in reproductive studies.

Fovea Centralis
An area approximately 1.5 millimeters in diameter within the macula lutea where the retina thins out greatly because of the oblique shifting of all layers except the pigment epithelium layer. It includes the sloping walls of the fovea (clivus) and contains a few rods in its periphery. In its center (foveola) are the cones most adapted to yield high visual acuity, each cone being connected to only one ganglion cell. (Cline et al., Dictionary of Visual Science, 4th ed)

Retinal Detachment
Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.

Granulosa Cells
Supporting cells for the developing female gamete in the OVARY. They are derived from the coelomic epithelial cells of the gonadal ridge. Granulosa cells form a single layer around the OOCYTE in the primordial ovarian follicle and advance to form a multilayered cumulus oophorus surrounding the OVUM in the Graafian follicle. The major functions of granulosa cells include the production of steroids and LH receptors (RECEPTORS, LH).
Swine
Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
Receptors, LH
Those protein complexes or molecular sites on the surfaces and cytoplasm of gonadal cells that bind luteinizing or chorionic gonadotropic hormones and thereby cause the gonadal cells to synthesize and secrete sex steroids. The hormone-receptor complex is internalized from the plasma membrane and initiates steroid synthesis.
Ear, Inner
The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (COCHLEA; VESTIBULAR LABYRINTH; and SEMICIRCULAR CANALS) in the TEMPORAL BONE. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (COCHLEAR DUCT; SACCULE AND UTRICLE; and SEMICIRCULAR DUCTS) forming a continuous space enclosed by EPITHELIUM and connective tissue. These spaces are filled with LABYRINTHINE FLUIDS of various compositions.

Uterus
The hollow thick-walled muscular organ in the female PELVIS. It consists of the fundus (the body) which is the site of EMBRYO IMPLANTATION and FETAL DEVELOPMENT. Beyond the isthmus at the perineal end of fundus, is CERVIX UTERI (the neck) opening into VAGINA. Beyond the isthmi at the upper abdominal end of fundus, are the FALLOPIAN TUBES.
Cyclooxygenase 2
Pregnenediones
RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Cholesterol Side-Chain Cleavage Enzyme
A mitochondrial cytochrome P450 enzyme that catalyzes the side-chain cleavage of C27 cholesterol to C21 pregnenolone in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP11A1 gene, catalyzes the breakage between C20 and C22 which is the initial and rate-limiting step in the biosynthesis of various gonadal and adrenal steroid hormones.
Immunohistochemistry
Retinal Pigment Epithelium
The single layer of pigment-containing epithelial cells in the RETINA, situated closely to the tips (outer segments) of the RETINAL PHOTORECEPTOR CELLS. These epithelial cells are macroglia that perform essential functions for the photoreceptor cells, such as in nutrient transport, phagocytosis of the shed photoreceptor membranes, and ensuring retinal attachment.
Prolactin
A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.

Macular Edema
Fluid accumulation in the outer layer of the MACULA LUTEA that results from intraocular or systemic insults. It may develop in a diffuse pattern where the macula appears thickened or it may acquire the characteristic petaloid appearance referred to as cystoid macular edema. Although macular edema may be associated with various underlying conditions, it is most commonly seen following intraocular surgery, venous occlusive disease, DIABETIC RETINOPATHY, and posterior segment inflammatory disease.

Perifoveal vascular leakage and macular oedema after intracapsular cataract extraction. (1/755)
Perifoveal capillary leakage of fluorescein was demonstrated in 60 per cent of 50 eyes when angiography was performed two weeks after cataract extraction. Repeat angiography six weeks postoperatively in 17 eyes demonstrated persistence of already established leakage in 11 of 12 eyes and no new leakage in five eyes previously negative. Cystoid macular oedema with visual acuity of less than 20/40 six weeks postoperatively occurred in five eyes (10 per cent). Eyes of patients with vascular disease and those patients of 60 years or older were found to have altered vascular permeability significantly more frequently. Inflammation was no more severe or prevalent in those patients who demonstrated leakage and no inflammation was clinically apparent in 10 of 11 eyes demonstrating dye leakage six weeks postoperatively. We conclude that the constitutional factors of age and vascular disease are of prime importance in causing altered vascular permeability in the early postoperative period after cataract extraction; factors causing sustained leakage with reduction of visual acuity were not demonstrated. (+info)The use of internal limiting membrane maculorrhexis in treatment of idiopathic macular holes. (2/755)
The purpose of this study was to assess surgical results of internal limiting membrane (ILM) maculorrhexis in macular hole surgery. This study is a part of continuing prospective clinical trial of our team of researchers. Thirteen eyes of 13 patients with idiopathic macular hole underwent vitrectomy with the removal of posterior cortical vitreous, peeling of the macular ILM, and intraocular gas tamponade, followed by postoperative face-down positioning. The excised specimens were evaluated with transmission electron microscopy. Complete closure of the hole was observed in all 13 eyes (100% anatomic success rate). Visual improvement of 2 or more lines on ETDRS visual acuity chart was achieved in 11 (85%) of the 13 eyes. Six (54.5%) eyes attained visual acuity of 20/50 or better. Electron microscopy showed ILM in the removed specimens. ILM maculorrhexis is a promising new surgical approach to close idiopathic macular holes but requires further investigation and long-term evaluation. (+info)Quantitative assessment of macular thickness in normal subjects and patients with diabetic retinopathy by scanning retinal thickness analyser. (3/755)
AIMS: To evaluate the scanning retinal thickness analyser (RTA), a novel non-invasive imaging instrument, in diagnosing and quantitatively characterising diabetic macular oedema, and to investigate the relation between central macula thickness measured by RTA and other clinical examinations. METHODS: Central macular thickness was measured using the RTA in 40 normal subjects and 60 patients with diabetic retinopathy. The reproducibility of the retinal thickness measurements was evaluated by calculating the mean of the inter- and intrasession variations. Central macular thickness was correlated with the results of visual acuity measurements, biomicroscopy, and fluorescein angiography. RESULTS: Intra- and intersession reproducibility of the RTA in normal subjects was plus or minus 5.2% (16 microns) and plus or minus 6.1% (19 microns), respectively. The mean central macular thickness was 182 (SD 16) microns in normal subjects, 283 (116) microns in diabetic eyes without clinically significant macular oedema (CSMO), and 564 (168) microns in diabetic eyes with CSMO. Central macular thickness was significantly greater (p < 0.001) in eyes with diabetic retinopathy than in normal subjects, even when macular thickening did not meet the standard for CSMO (p = 0.019) measured by biomicroscopy. Although greater fluorescein leakage at the macula results in greater central macular thickness, only eyes with diffuse leakage had statistically significant macular thickening compared with normal subjects (p = 0.022). Central macular thickness measured with the RTA was significantly correlated with the logarithmic converted visual acuity (r2 = 0.76) in diabetic eyes. CONCLUSION: Scanning RTA, which has good reproducibility, might be useful to quantitatively detect and monitor macular thickening in diabetic retinopathy. Central macular thickness was highly correlated with logarithmic converted visual acuity in diabetic macular oedema. (+info)Natural history of diabetic macular streak exudates: evidence from a screening programme. (4/755)
BACKGROUND/AIMS: Diabetic retinopathy screening guidelines recommend referral to an ophthalmologist if there is exudate within one disc diameter of the fovea. Many of these patients, however, have resolution of small amounts of exudate without treatment. This study aimed to assess whether patients with minimal streak or dot exudates within one disc diameter of the fovea can be monitored in a screening programme without compromising visual acuity. METHODS: A retrospective review of records and Polaroid photographs obtained by one screening centre over a 10 year period was performed. Outcomes measured were referral rates, alteration of Snellen visual acuity, and the need for macular photocoagulation treatment. RESULTS: 55 patients (74 eyes) fulfilled entry criteria (37 streak and 37 dot exudates). Mean follow up was 56.1 months (range 12-127 months). Twenty five patients (30 eyes) were referred to an ophthalmologist. 13 eyes (17.6%) required macular photocoagulation treatment. Four eyes (5.4%) lost two or more lines of Snellen acuity over the follow up period (three from macular oedema and one from macular ischaemia). There was no relation between the presence or resolution of minimal exudate and visual loss (p>0.2). CONCLUSION: It is appropriate to monitor eyes with streak or dot macular exudates at 6-9 monthly intervals in a screening programme. (+info)Macular vasculopathy and its evolution in incontinentia pigmenti. (5/755)
PURPOSE: To describe macular vasculopathy in incontinentia pigmenti. METHODS: Twelve baby girls with incontinentia pigmenti were examined under general anesthesia by fluorescein angiography of the macula. Nine eyes of 9 patients had sufficient detail to allow evaluation of capillary changes. Angiography was initiated as early as 3 months of age and was repeated in 7 eyes at 3- to 12-month intervals. Changes in capillary patterns were identified. RESULTS: Irregularly enlarged or distorted foveal avascular zones were noted in all 9 maculas. Sparseness of the perifoveolar capillary bed was a characteristic finding. Sequential macular angiography demonstrated non-progressive (stable) capillary closure in 2 eyes; progressive closure in another macula; progressive closure plus addition or reopening of macular capillaries in 3 eyes; and central retinal artery occlusion, with cherry-red spot formation, in 1 eye at 12 days of age. In addition, progressive tractional detachment of the macula occurred in 2 of these eyes, and progressive macular neovascularization occurred in 1 eye. CONCLUSIONS: Macular ischemia is characteristic of incontinentia pigmenti and is often progressive. It is the initiating event of a typical vasculopathy, characterized by capillary remodelling and, occasionally, by neovascularization and tractional detachment of the retina. (+info)The etiology and treatment of macular detachment associated with optic nerve pits and related anomalies. (6/755)
PURPOSE: Up to two thirds of patients with optic disc pits develop a sight-limiting maculopathy. There is confusion regarding the etiology and nature of the maculopathy in these cases. We present 7 cases of serous macular detachment occurring in association with optic pits or related cavitary anomalies and identify a rhegmatogenous etiology. METHODS: We reviewed the records of 7 patients with optic nerve anomalies and macular detachment. Patients were treated with observation, barricade laser, vitrectomy, and/or gas tamponade. RESULTS: Seven patients were noted to have serous macular detachment associated with an optic nerve pit or other cavitary anomaly. A hole or tear in the diaphanous tissue overlying the optic pit was identified in all cases. None of the patients had a posterior vitreous detachment. Two were treated with photocoagulation only, and 5 underwent pars plana vitrectomy with fluid-gas exchange with or without photocoagulation. Pretreatment visual acuity ranged from 20/30 to 6/200. Posttreatment acuity ranged from 20/25 to 20/100. Five of 7 eyes had final acuities of 20/30 or better, and all treated eyes improved. CONCLUSIONS: A tear in the diaphanous tissue overlying the optic nerve pit is responsible for the development of serous macular detachment and is consistent with findings in similar conditions, such as retinal detachment in association with chorioretinal coloboma. These tears may be quite subtle, and careful biomicroscopic examination is required to appreciate them. The treatment of this condition remains controversial. However, because of the relatively poor prognosis, we believe treatment should include the formation of a barricade to fluid movement as well as sealing and relief of traction from the hole. The value of laser treatment may be increased by the early identification of a defect in the diaphanous membrane prior to the development of macular detachment. Consideration of prophylactic laser might then reduce the need for later, more invasive measures, and improve the prognosis. (+info)The spectral sensitivity of the human short-wavelength sensitive cones derived from thresholds and color matches. (7/755)
We used two methods to estimate short-wave (S) cone spectral sensitivity. Firstly, we measured S-cone thresholds centrally and peripherally in five trichromats, and in three blue-cone monochromats, who lack functioning middle-wave (M) and long-wave (L) cones. Secondly, we analyzed standard color-matching data. Both methods yielded equivalent results, on the basis of which we propose new S-cone spectral sensitivity functions. At short and middle-wavelengths, our measurements are consistent with the color matching data of Stiles and Burch (1955, Optica Acta, 2, 168-181; 1959, Optica Acta, 6, 1-26), and other psychophysically measured functions, such as pi 3 (Stiles, 1953, Coloquio sobre problemas opticos de la vision, 1, 65-103). At longer wavelengths, S-cone sensitivity has previously been over-estimated. (+info)A practical method for measuring macular pigment optical density. (8/755)
PURPOSE: Increasing evidence indicates that the macular pigments (MP) protect the central retina and may retard macular disease. For that reason, a practical method for measuring MP that does not require elaborate optics and can be applied to diverse populations by operators with a modest amount of experience was developed and validated. METHODS: A small tabletop device based on light-emitting diodes (LEDs) as the light source with electronic controls was constructed. Macular pigment was measured with the tabletop device with a 1 degrees test stimulus at 460 nm using heterochromatic flicker photometry, and the results were compared with measurements using a traditional three-channel Maxwellian view system with a xenon-arc source. RESULTS: Macular pigment density of 30 subjects (age range, 16-60 years) was measured with both stimulus systems. Macular pigment measured with the LED tabletop device in free view was highly correlated with MP measured in Maxwellian view (y = -0.03 + 1.06x, r = +0.95). The average absolute difference between the two techniques was 0.04 (SD, 0.03). The new technique was not significantly affected by variations in lens optical density, pupil size, or small head movements. CONCLUSIONS: Psychophysical measurement of MP provides a unique opportunity to make repeated noninvasive assessment of the concentration of a protective nutrient in the retina. The availability of this new device should make this measurement technology accessible to a wide variety of investigators for application to diverse populations. (+info)
