Hemi Retinal Vein Occlusion a Particular Form of Retinal Vein Occlusion

We report a case of 55-year-old women, with a medical history of hypertension and diabetes, who complained of a sudden loss of vision of her left eye. Her VA was less than 20/200; slit lamp and gonioscopy were unremarkable. Dilated fundus examination had shown an Aspect of HRVO with a Thunder of flame shaped retinal hemorrhages covering the inferior half of the retina, tortuous veins and cotton-wool spots.

Adeno Squamous Palpebral Carcinome with Orbitary Extension: Case Report

Adeno-Squamous Carcinoma (ASC) is a neoplastic variety characterized histologically by the presence of 2 distinct carcinomatous contingents, adenomatous and squamous. This tumor form is extremely rare, and even more so in its palpebral localization. In the light of this observation, we will expose the anatomo-clinical and evolutionary peculiarities of this uncommon variant.

Terminological and Metrological Aspects in Siepser-Type Iris Suture Procedures

Instead of contemporary plethora, with tenths of different terms for only 7 elements, I suggest a system in which the main criterion is the length of the 2 filament ends just before the loop is externalized: L: long end, and S: short end. The name of the 2 corneal pathways, and 2 iris bites will rely on the name of the corresponding filament end that passes through, just before the loop is externalized: Sp/SP: short-end puncture/paracentesis, Lp/LP: long-end puncture/paracentesis, SIB: short-end iris bite, LIB: long-end iris bite. When the loop is externalized, the “intermediary segment”: (I) is created from L. The limits of (I) have been adjusted: instead of generally admitted limits from the middistance between SIB and LIB, to the middle of the externalized loop, I suggest that the S/(I) limit be situated at 1mm after the exit point of the loop from SP, and the (I)/L limit be situated at the re-entry point of the loop in SP. The suggested terminology and limits of (I) allow a clear and unequivocal description of techniques, simplify the repartition of functions per filament segment, avoid misunderstanding as cause of failure, facilitate the establishment of rules for success valid in any Siepser-type suture, and allow a new systematization of all iris suture procedures in a structure with a common stem, 2 branches (McCannel, Siepser) and leaves represented by technical variants.

Phakochronology - The Forgotten Science

A 30 year old male, had history of bomb blast injury to the face 24 months ago with multiple foreign bodies perforating the eye (operated for vitrectomy and foreign body explant). The iris entry wound and the cataract caused by one such foreign body is shown in (Figure 1a). The opacity in the lens substance (Figure 1b) is 156 microns behind the anterior lens capsule (Figure 1c) (meaning growth of these much lens fresh clear lens fibres over the time has pushed the lens opacity backwards which earlier would have been on the surface). Calculating by phakochronology [1], we would like to report the in-vivo lens growth in this patient to be 6.5 microns/month.

Congenital Anophtalmia: Two Cases Report

Anophthalmia is a rare condition that is estimated to have an incidence of 1 in 10 000 live births. These ocular malformations may be unilateral or bilateral, and may be isolated or occur with other malformations as part of a syndrome. The etiology is heterogeneous and remains unknown. Prenatal diagnosis, which is now available, allows for the early diagnosis of these diseases and the identification of other malformations or signs that may prejudge the prognosis, which must be carefully explained to parents. The prognosis is variable and depends on severity, associated abnormalities and the underlying genetic cause. Reported cases of anophthalmia generally represent severe microphthalmia; true primary anophthalmia is rarely compatible with life secondary to associated brain abnormalities.
