“…In a study by Gortzak et al, 9 40 patients with vernal catarrh and 36 controls were studied and the maximum corneal power in vernal catarrh group was 44.975.1 D and in the control group it was 42.971.9 D.…”

“…Although corneal changes in VKC are well documented, [7][8][9][10][11] there has been no study on corneal changes in patients with steroidinduced glaucoma and VKC using a slit scan topography system. This study was designed to study the corneal topographic changes associated with steroid-induced glaucoma in eyes with VKC and the effect of reduction in intraocular pressure on the corneal variables.…”

Purpose: To study the corneal topographic response to IOP reduction in vernal keratoconjunctivitis (VKC) with steroidinduced glaucoma. Methods: A total of 42 eyes of 21 patients with VKC and steroid-induced glaucoma (Group I) and 66 eyes of 33 patients with VKC without glaucoma (Group II) underwent an evaluation by Orbscan topography. In eyes with glaucoma, the IOP was controlled medically and the corneal topography was repeated at 3 months to evaluate effect on corneal parameters. Results: The mean baseline IOP was 36.40713.08 mmHg in Group I, 14.6774.62 mmHg in Group II (Po0.0001). The IOP after treatment at 3 months follow-up was 15.0075.41 mmHg in Group I (Po0.0001). In Group I, the mean maximum Sim K decreased from 44.8673.21 D to 43.8772.62 D (P ¼ 0.031) and mean posterior corneal elevation decreased from 64.9722.36 lm to 35.7728.91 lm at 3 months after reduction of IOP (P ¼ 0.001). There was a significant positive correlation between the reduction in the IOP and the decrease in the posterior corneal elevation (r ¼ 0.664, P ¼ 0.001). Conclusion: Eyes with VKC with and without glaucoma have similar corneal topography. Increased IOP associated with steroid-induced glaucoma and VKC may contribute to an increase in the corneal curvature and posterior corneal elevation. These changes may be reversed by a reduction in the IOP with medical therapy.

“…VKC was seen to be more commonly present in males (82.3%) similar to previous studies. (11)(12)(13)(14)(15)(16) All studies reported late presentation of keratoconus in VKC patients except Gortzak et al (15) Dantas et al report, palpebral VKC (97.81%) was more common in patients having keratoconus whereas mixed VKC (36.50%) was more common in our study. (17) Sixty four (30.47%) were found to have suspected keratoconus-like topography as compared to 10.7% by clinical criteria in our study.…”

“…(14) These studies used the modified Rabinowitz-McDonnell criteria. (15)(16)(17) whereas, we used pathfinder II corneal analysis using machine Carl zeiss meditec inc USA model ATLAS 9000 specially sensitive to early detection of keratoconus. Pathfinder II corneal analysis has sensitivity and specificity of >90% to detect abnormal corneas as reported by preliminary report in large multicentric clinical trials.…”

BACKGROUND:Vernal keratoconjuctivitis has a known association with keratoconus. OBJECTIVE: Study was conducted to evaluate corneal topographic characteristics of patients with vernal keratoconjunctivitis (VKC) and compare the corneal topographic indices in VKC subjects with normal subjects. STUDY DESIGN: Prospective comparative study. MATERIAL AND METHODS: Videokeratography was done in 210 consecutive VKC patients and 201 age and sex matched normal subjects by Carl Zeiss meditec inc USA to evaluate corneal topography. Other tests included visual acuity testing with Snellens chart, slit lamp biomicroscopy, dilated fundus examination, measurement of central corneal thickness and intraocular pressure. Topographic indices were analyzed and compared using unpaired t-test among different groups. RESULT: Among 210 subjects with VKC, males comprised of 173 patients (82.3%) and mean age of presentation was 11.5±4.6 years with mixed VKC in 60%. Keratoconus-like topography was present in 64 patients (30.47%). CONCLUSION: Keratoconus-like topography was observed in very high proportion of patients of VKC.

Pressure to practice evidence-based medicine is increasing and has the potential to reduce malpractice claims. Sometimes the evidence may prove a specific therapy to be ineffective, but practice says it is effective. In Medicine, however, if you do not trust the evidence, you may expose yourself and your patients to untoward consequences. When we face a complex problem, most of the time it is better to rely on scientific evidence rather than on expert personal opinion.
