    Corneal epithelial damage and impaired tear functions in patients with inflamed pinguecula
    (Hindawi Limited, 2018) Küçük E.; Yilmaz U.; Zor K.R.
    Purpose. In this study, we evaluated corneal epithelial integrity and tear film parameters in patients with inflamed pinguecula and compared these findings with their fellow eyes and with healthy controls. Methods. We evaluated the fluorescein staining properties and performed the tear break-up time (TBUT) test and Schirmer 2 test (ST2) measurements of 32 patients who had symptomatic unilateral inflamed pinguecula and compared the results with their fellow eyes and also with an age- and sex-matched control group. Results. Twenty-three eyes (72%) in the inflamed pinguecula group and 1 eye (3.1%) in the fellow eyes group had punctate epithelial staining (PES) or epithelial defect on the nasal cornea (p < 0.001).There was no PES or epithelial defect in the control group. Eyes with inflamed pinguecula (n = 32) had lower TBUT and ST2 values compared to the control group (n = 32) (p < 0.001 for both). Fellow eyes (n = 32) also had lower TBUT and ST2 values compared to the control group (p =0.003 for both).There was no difference in the TBUT and ST2 results between the eyes with inflamed pinguecula and fellow eyes (p =0.286 and p = 0.951, respectively). Conclusion. A high percentage of eyes with inflamed pinguecula had nasal corneal epithelial staining or epithelial defect. We also found lower TBUT and ST2 results in eyes with inflamed pinguecula and the fellow eyes compared to the control group.These findings may be important in pathogenesis of pinguecula and pterygium and also in uncovering their relation. © 2018 ErkutKüçük et al.

    Ocular findings in posterior microphthalmos
    (Elsevier B.V., 2019) Zor K.R.; Küçük E.; Günaydın N.T.; Önder F.
    Aim: To report a critical case series of six patients with posterior microphthalmos (PM). Method: Complete ophthalmologic examinations of all patients were performed using best-corrected visual acuity (BCVA), cycloplegic refraction, applanation tonometry, slit lamp biomicroscopy of the anterior segment, fundoscopy, A and B mode ultrasonography (USG), keratometry, and optic coherence tomography (OCT). Results: The most significant clinical characteristics of male patients aged 10–25 years was the presence of shorter posterior segments (mean: 15.27–18.91 mm) accompanying high hyperopia (mean +9.00 – +18.50 diopter) despite the normal anterior segment findings. The BCVA ranged between 20/320 and 40/100. Retinal folds were detected bilaterally on the papillomacular band in all patients. Although neurosensory retina was included in the fold in OCT images, retinal pigment epithelium, choroid, and sclera were not included in the fold. Pigmentary retinopathy was detected in one patient. Conclusion: Despite normal anterior segment, posterior microphthalmos is characterized with high hyperopia, and shorter axial length and bilateral papillomacular retinal fold. Refractive amblyopia, uveal effusion syndrome, retinal detachment and macular hole are complications that can be corrected. Posterior microphthalmos must be kept in mind in patients with a normal anterior segment, and high hyperopia. © 2018 The Authors
