purpose: to introduce the technique and results of vitrectomy surgery with removal of cyclitic membrane by placement of radial cuts over the membrane in traumatized eyes. methods: vitrectomy in 8 eyes of 8 patients after penetrating ocular trauma revealed that fibrovascular tissue was present over the pars plicata. to remove the membrane, radial cuts were placed over the membrane first and then...

This study reports the histological findings in human eyes after severe penetrating trauma. The findings confirm the high incidence of retinal detachment in eyes with severe penetrating injuries. The retina was detached in 32 out of the 34 eyes examined, with 27 having evidence of traction on the retina. These eyes were characterized histologically by intraocular cellular proliferation producin...

The popularization of ophthalmic endoscopy has been promoted by recent technological advancements that increase the number of indications for endoscopy. These advancements have improved the endoscope's capabilities in its two fundamental surgical advantages: (1) bypassing anterior segment opacities, and (2) visualizing anteriorly positioned structures such as the ciliary bodies and sub-iris spa...

The transfer coefficients of fluorescein in the anterior chamber by flow, kfa, and by diffusion, kdpa, can be calculated for an individual human eye, through an analysis of fluorescein concentrations in the anterior chamber, pupillary aqueous, and serum ultrafiltrates following intravenous injection. Using this technique, aqueous humor dynamics was studied in eight patients with glaucomato-cycl...

The histological findings of the wound, the vitreous, and the retina in the rabbit eye with experimental posterior penetrating injury are described. Wound healing had just begun at 3 days after injury and was well established by 9 to 12 days. It involved proliferation of cells from the episclera and from the choroid. The progression to a fibrous ingrowth from the wound occurred only in eyes wit...

The ocular pathology of sympathetic ophthalmia is demonstrated in a 10 year-old boy who sustained a penetrating left globe injury and subsequently developed sympathetic ophthalmia in the right eye two months later. Two and a half weeks following extensive surgical repair of the left ruptured globe, he developed endophthalmitis and was treated with oral and topical fortified antibiotics. One mon...

Purpose: To report a case of fulminant Streptococcus mitis endophthalmitis after intravitreal injection of aflibercept. Methods: Retrospective case report Results: An 83-year-old man presented with acute painful vision loss in his left eye approximately 20 hours after intravitreal injection of aflibercept. His vision had decreased from a baseline of 20/100 to barely hand motion in the left eye ...

PURPOSE To evaluate the influence of irrigation of the anterior chamber with heparin sodium on postoperative inflammation after pediatric cataract surgery. SETTING Kartal Training and Research Hospital, First Eye Clinic, Istanbul, Turkey. DESIGN Randomized prospective double-blind study. METHODS Fourteen consecutive eyes from 14 patients aged 8.9 +/- 5.9 years, (range 3-18 years) (group 1...
