Anatomic outcome of scleral buckling surgery in primary rhegmatogenous retinal detachment.

PURPOSE: To evaluate the factors affecting the anatomic success of treatment of retinal detachments (RD) by scleral buckling surgery. METHODS: One-hundred and two eyes of 102 patients with rhegmatogenous RD operated on by scleral buckling surgery were included in the study. Results were analyzed according to the anatomic status of the retina at the most recent follow-up examination. The chi-squared test was used to determine the relationship between preoperative and intraoperative variables and anatomic results, and the relative risk of failure was determined for each variable. RESULTS: Retinal reattachment was achieved in 85 of 102 eyes (82.5%) after initial surgery. The success rate for anatomic reattachment was 95% after two operations. After three operations reattachment was achieved for 98 eyes (96%). Predictive factors for anatomic failure (P<0.05) were the presence of grade C(1) PVR and multiple breaks. CONCLUSION: Grade C(1) PVR and multiple breaks were found to be significant risk factors for anatomic failure in rhegmatogenous RD treated by conventional buckling surgery.

A simple "lasso" for intraocular foreign bodies.

Three patients had foreign bodies in their anterior chambers following penetrating ocular injuries. These foreign bodies were removed by a closed chamber technique using a simple loop. The loop was created by a 22-gauge intravenous cannula and a 7-0 polypropylene suture. Retained cilia in one patient and metallic foreign bodies in two patients were removed using this intraocular "lasso." Sutures were not placed at the incision sites at the end of the surgery. This is an inexpensive and easy to prepare technique that introduces minimal surgical trauma. In addition, two hands are not needed for loop manipulation. This technique may be an excellent alternative for removal of small intraocular foreign bodies.

Hypotony: an unusual consequence of intraocular lens malposition.

Common causes of postoperative hypotony include wound leakage, inflammatory reaction of the ciliary body, cyclodialysis, and ciliochoroidal detachment. We present an unusual case of ocular hypotony in a pseudophakic eye associated with distortion of the ciliary body by a decentered posterior chamber intraocular lens (IOL) haptic. A simple surgical repositioning of the IOL relieved the hypotony by eliminating the irritation by the IOL haptic on the distorted edematous ciliary body. Ciliochoroidal irritation by IOL haptics should be considered a possible cause of ocular hypotony in a pseudophakic eye.

Tilt and decentration of bag-fixated intraocular lenses: a comparative study between capsulorhexis and envelope techniques.

Malposition of an intraocular lens (IOL) may cause symptoms such as glare, halos, and other visual aberrations. The purpose of this study is to determine the effect of two different anterior capsulotomy techniques on IOL tilt and decentration. Bag-fixated IOL implantation after uncomplicated extracapsular cataract extraction was performed using both envelope (65 eyes) and continuous circular capsulorhexis (CCC) technique (42 eyes). Eyes were followed-up at least 6 months postoperatively. While the mean IOL decentration after envelope technique was found to be 0.65 mm, this was 0.15 mm after CCC technique. On the other hand, the mean actual tilting angle of IOL after envelope technique was 5.66 degrees, whereas this was 1.13 degrees after CCC technique. The aforementioned differences were statistically significant (p < 0.01, and p < 0.01). Furthermore, in 17 eyes (26.1%) where envelope technique and in 29 (69.0%) eyes where CCC technique was used demonstrated no IOL tilt and decentration. This study shows that the CCC technique may result in less optical problems due to IOL malposition compared to the envelope technique.

Serum and aqueous humor sialic acid levels in Behçet's disease.

Serum and aqueous humor sialic acid (SA) levels were determined in 27 patients with Behçet's disease (Bd). Serum SA levels were elevated significantly during the active episode (mean, 113.4 +/- 4.12 mg/dl) and in the remission stages (mean, 85.4 +/- 4.79 mg/dl; P less than 0.001). A significant increase was also detected in active episodes when compared to chronic stages (P less than 0.02). Aqueous humor levels were also evaluated but could only be determined in the six eyes at the end-stage of the disease (mean, 2.65 +/- 0.60 mg/dl; P less than 0.05).

Determining fluid level in a translucent eye-drop bottle: transillumination by penlight.

We describe an easy way to determine eye-drop contents in translucent bottles. Transillumination of eye-drop bottles from behind or the bottom by using a penlight clearly defines the fluid levels. The described procedure may prevent disposal of eye-drop bottles containing useful amounts of medication and prevent Ophthalmologists and Patients unexpectedly coming across an empty bottle.

Alcohol liberates dye of syringes.

Foreign particles may contaminate intraocular surgery and have a role in postoperative inflammation. Irrigation solutions, viscoelastics, air and instruments introduced into the eye may carry in a number of organic or inorganic, inert or reactive foreign material. Dye of colored indicators on syringes may also behave as an unrecognized contaminant. This dye material is easily released from syringes by exposure to alcohol. The significance of dye contamination and possible outcomes were discussed.

Coexistence of intraocular eyelashes and anterior chamber cyst after penetrating eye injury: a case presentation.

We herein describe a patient in whom two intraocular eyelashes and an anterior chamber cyst embedded into the anterior surface of the iris was detected following penetrating eye injury. After a one year asymptomatic period, the patient was hospitalized because of uveitic reaction in the anterior chamber which may be due to cyst development. The lashes and cyst were removed surgically, and examined pathologically. There was no complication in one year follow-up period.

A novel suture technique in stellate corneal lacerations.

A novel suture technique for regular stellate corneal lacerations, called a star-shaped suture is described. The suturing begins from inside any of the wound lips in a clockwise direction. Suture placement proceeds in a counterclockwise direction by the adjacent wound limb, while the suture passes are all in clockwise direction. Finally, a star-shaped suture is achieved with the knot self-buried in the corneal stroma at the initial entry site. This is a continuous suture, of which tractional forces direct to the center of the wound providing good apical apposition for stellate lacerations. This suture technique can be an alternative for the reconstruction of stellate corneal lacerations.
