Uncontrolled overuse of TAD can lead to serious ocular morbidities. Similarity of the clinical signs of this abuse to those of infectious keratitis together with the fact practitioners and managers to take measures to prevent the ready supply of these drugs from pharmacies and to raise public awareness with education programs.

PURPOSE: Applied pre- and postoperative corneal topography outcomes with visual acuities were evaluated to determine the surgical results in pterygium therapy. METHODS: The study group consisted of 30 eyes of 26 patients with primary and recurrent pterygium. Mean patient age was 52.26±11.50 years (range: 27 to 68 years). Pre- and postoperative visual acuity and corneal topography were evaluated for each case. Statistical analysis was performed using the repeated-measure test. RESULTS: The mean uncorrected visual acuity was 0.41±0.30 preoperatively and 0.63±0.26 postoperatively (P<.001). The mean best spectacle-corrected visual acuity was 0.59±0.28 preoperatively and 0.84±0.22 postoperatively (P<.001). Surface regularity index ranged from 1.96±1.08 preoperatively to 1.09±0.76 postoperatively (P<.001). The mean surface asymmetry index was 3.05±2.85 preoperatively and 1.39±1.70 postoperatively (P=.003). The mean topographic astigmatism was 4.65±3.02 preoperatively and 2.33±2.26 postoperatively (P=.003). CONCLUSIONS: Examination of the topographic records reveals pterygium-associated corneal flattening in the horizontal meridian along the line of the pterygium. The improvement in topographic pattern and best spectacle-corrected visual acuity can be used as one indicator of the success of pterygium surgery. [J Refract Surg. 2005;21:166-170.]

To study the efficacy and safety of sutureless amniotic membrane transplantation combined with narrow-strip conjunctival autograft and to investigate the clinical outcomes. Thirty eyes of 30 patients with primary pterygia were treated in this institutional study with excision followed by sutureless amniotic membrane transplantation combined with narrow-strip conjunctival autograft using fibrin glue tissue adhesive. The main outcome measures were the operating time for ocular surface reconstruction, the size of the pterygium and of the conjunctival autograft, postoperative complications, subjective complaints, and recurrences. The mean pterygium size was 3.12 ± 0.92 mm and the mean operating time was 4.58 ± 1.10 min. Twenty-nine patients (96.7%) had no complaints after first postoperative week. Twenty-eight (93.3%) patients had no recurrences after 1 year follow-up. The sutureless amniotic membrane transplantation combined with narrow-strip conjunctival autograft is an effective procedure with low rate of recurrence. This technique can be considered as a preferred grafting procedure for primary pterygium but further randomized controlled studies including larger populations are needed.

Purpose: To evaluate the results of surgical management of scleral defects using fascia lata, cornea, and sclera as graft materials. Methods:The scleral defects of 8 patients were repaired surgically.Six had previous intraocular surgery, 1 had eye trauma, and the other had both intraocular surgery and trauma. Corneoscleral grafts were used in 3 eyes, scleral grafts in 4, and fascia lata was used in 1 eye. Results:In 7 patients, we achieved the desired cosmetic and tectonic success. During the follow-up period, a recurrent defect was seen in 1 patient, and a second operation was required.Conclusions: Surgical techniques using fascia lata, corneal, and scleral grafts are effective for scleral defects.

New techniques are being searched for the evaluation of cellular morphology and population of ocular surface. Impression cytology is one of the most preferred techniques in ocular surface sampling in dry eye, keratitis, and conjunctivitis. We evaluated and compared the efficacy of impression and brush cytology in 63 patients. All of the samples collected by the brush technique were sufficient for diagnosis: 88% of the slides revealed abundant cells and 12% adequate number of cells. In 21% of the samples observed by impression cytology the cell number was inadequate for diagnosis. In 58% of them the cells were abundant and in 21% few cells were observed. This study proved the value of brush cytology in collecting ocular surface cells. Diagn. Cytopathol. 17:88–91, 1997. © 1997 Wiley‐Liss, Inc.

Ropivacaine used in peribulbar block is better than bupivacaine-lidocaine mixture under the same standard conditions in terms of reducing intraocular pressure and postoperative pain in intraocular surgery.
