Abstract
PURPOSE To evaluate the in vitro efficacy of cidofovir, ganciclovir, povidone-iodine, chlorhexidine, and cyclosporine A on adenovirus genotype 8. METHODS Conjunctival samples were collected from patients with adenoviral conjunctivitis and cultured in A549 cells. Adenovirus diagnosis was confirmed by RT-PCR. For each drug, the 50% cytotoxic concentration (CC 50 ) was determined. Subsequently, the antiviral activity was tested at concentrations below CC 50, and the 50% inhibitor concentration (IC 50 ) of drugs was determined RESULTS: While the IC 50 of cidofovir against adenovirus genotype 8 was 3.07 ± 0.8 µM, ganciclovir, povidone-iodine, chlorhexidine, and cyclosporine A were not found to be effective against adenovirus genotype 8 at concentrations below the CC 50 value. CONCLUSIONS Cidofovir was found effective and the IC 50 value was within the ranges in the literature. Ganciclovir and cyclosporine A were found to be ineffective at doses below the cytotoxic dose, povidone-iodine and chlorhexidine was found to be highly cytotoxic.

Abstract
The study aimed to evaluate the relationship between clinical findings and viral load in adenoviral keratoconjunctivitis (Ad-Kc). In this cross-sectional study, 30 eyes of 30 patients with Ad-Kc were enrolled. The real-time polymerase chain reaction was performed to detect and quantify adenovirus in all samples. The patient groups were divided into three subgroups according to baseline viral loads (<107, 107-108, >108 HAdV copies/ml). The follow-up duration, HAdV DNA copy number, treatment regimen, and detailed clinical findings including uncorrected visual acuity, eyelid edema, conjunctival hyperemia, chemosis, follicular reaction, corneal involvement, conjunctival pseudomembrane, and subepithelial infiltrates (SEIs) were recorded. The study showed that a high initial viral load was associated with the development of SEIs and pseudomembrane formation (p<0.05). Clinical findings and ocular complications of Ad-Kc were found similar in treatment groups at the final visit (p>0.05). Our results showed that a high initial viral load in Ad-Kc may be predictive of inflammatory sequelae. Determination of the initial viral load in Ad-Kc may be helpful to better understand the clinical course of the disease and prevent complications.

Abstract
PURPOSE This study aimed to evaluate the visual performance of extended range, toric soft contact lenses (TSCLs) in patients with keratoconus and moderate to high astigmatism with different astigmatic patterns. METHODS This was a retrospective, cross-sectional clinical study. Extended range TSCL users with astigmatism ≥3.0 D were included. Cases were categorised into three subgroups, namely regular, irregular (non-keratoconus) and keratoconic based on the topographic pattern of astigmatism. In addition, subjects were subdivided based on the degree of astigmatism. RESULTS Fifty five patients (82 eyes) were enrolled, of whom 28 (51%) were female. The mean age was 24.2 ± 7.5 (range: 8-41 years) years. Thirty-six eyes with regular astigmatism (43.9%), 34 eyes with irregular astigmatism (41.5%) and 12 eyes with keratoconus (14.6%) were included. The percentage improvement in visual acuity (VA) was significantly higher with contact lenses compared with spectacles in all groups (p < 0.001), with the highest improvement in subjects with keratoconus (p = 0.03). Twenty six (31.7%), 30 (36.6%) and 26 eyes (31.7%) had moderate (-3.0 to -4.24 D), moderate/high (-4.25 to -5.99 D) and high (≤-6.0 D) astigmatism, respectively. The percentage improvement in VA with contact lenses was statistically significantly higher than for spectacle wear in all groups (p < 0.001). CONCLUSIONS This study demonstrated that satisfactory visual outcomes can be obtained with extended range TSCLs in patients having moderate to high astigmatism with different astigmatic patterns.

Abstract
OBJECTIVES The study aimed to assess the possible effects of corneal cross-linking (CXL) on contact lens (CL) fitting in patients with progressive keratoconus who initially had CL intolerance. METHODS A retrospective review was performed of the medical records of patients who had stopped CL wear due to discomfort prior to CXL and who were fitted with CLs after CXL. All eyes were evaluated pre- and 1, 6, 12, 24 months postoperatively. Data collected included pre- and post-CXL refraction, corneal topographic data, uncorrected visual acuity, and best-corrected visual acuity (BCVA). CL comfort was evaluatedusing theLikert scale post-CXL. RESULTS A total of 20 eyes from 14 patients were included in the study. Preoperative Kmax values significantly decreased by 2.8 D at 6 months and by 4.1 D at 12 months after CXL (p < 0.001 for both). CLs were prescribed on average 12 ± 2.5 months after CXL. The mean duration of successful CL wear was 10.4 ± 2.8 months during the follow-up period. Subjective CL comfort scores were satisfactory post-CXL. CONCLUSION CXL not only halts the progression of keratoconus but may also improve CL tolerance by providing a more regular shaped cornea in these patients. Ongoing corneal topographic changes in the late postoperative period after CXL may have a positive effect on CL fitting.

Abstract
INTRODUCTION To evaluate the safety and efficacy of new-generation hybrid contact lenses (HCL) among patients with irregular astigmatism. METHODS Medical records of 25 patients fit with new-generation HCL (Eyebrid® and AirFlex®) were retrospectively reviewed. The data collected included etiology of irregular astigmatism, uncorrected visual acuity, manifest refraction, spectacle-corrected visual acuity (S-CDVA), steep / flat keratometric values, corneal astigmatism, records of rigid / soft CL fitted before HCL, all parameters of the trial lenses, and the final prescribed HCL parameters and HCL-CDVA. RESULTS The study included 34 eyes from 25 patients (nine females and 16 males) with an average age of 29 ± 13 (ranging from 8-56) years. In total, 25 eyes with keratoconus, four with post - keratoplasty astigmatism, three with irregular astigmatism due to corneal trauma and two with residual astigmatism after radial keratotomy were fit with HCL. The mean S-CDVA (logMAR) improved significantly from 0.76 ± 0.41 to 0.14 ± 0.15 with HCL (p < 0.01). The most common indication for HCL was inability to fit with rigid gas permeable (RGP) lenses (22 eyes). The average number of lenses to successful fit was 1.4 (mode, 1; median, 1) and ideal fit was achieved with the first trial lens in 25 eyes (73%). Seven patients (nine eyes, 36%) discontinued lens use within the first 6 months because of discomfort (six eyes, 24%), ocular allergy (two eyes, 8%) and tearing of contact lens (one eye, 4%). DISCUSSION New-generation HCL may be a suitable option for fitting challenging corneas with irregular astigmatism that cannot be rehabilitated efficiently with rigid lenses.

Abstract
A 45-year-old man presented with a 3-month history of a mass located in the caruncle of his right eye. An incisional biopsy had been performed one month prior by another specialist, and the histopathology report showed basal cell carcinoma. The mass was completely excised with a 2 mm safety margin, and the large conjunctival defect was reconstructed with one sheet of amniotic membrane allograft. A histological diagnosis of pilomatrix carcinoma was established. To prevent recurrence after surgery, we added bevacizumab (25 mg/mL, 1.25 mg/mL per drop) eye drops four times per day for three months. At the one-year follow-up, the patient showed no evidence of local recurrence or distant metastasis after initial excision and remains under close follow-up. Pilomatrix carcinoma should be considered in the differential diagnosis of a caruncular mass.

Abstract
Purpose: To evaluate the effectiveness of intraductal meibomian gland probing in addition to conventional treatment for the management of obstructive meibomian gland dysfunction (O-MGD).Methods: Totally, 40 patients were divided into two groups to receive either conventional treatment alone (group 1: 40 eyes of 20 patients) or conventional treatment plus probing (group 2: 40 eyes of 20 patients). The ocular surface disease index score, Schirmer 1 test, tear film break-up time, Oxford grading of ocular surface, meibum expressibility, and quality scores were evaluated baseline and compared with the end of treatment (day 30 and day 90).Results: There was no significant difference in baseline scores between groups (All p > 0.05). All scores demonstrated significantly improvement from baseline in both group, and it was faster in group 2 (All p < 0.05).Conclusion: This study showed that intraductal meibomian gland probing seems to provide rapid symptom relief and clinical improvement for patients with O-MGD.

Abstract
PURPOSE To evaluate the efficiency of corneal collagen cross-linking (CXL) in addition to topical voriconazole in cases with mycotic keratitis. DESIGN Retrospective case series in a tertiary university hospital. PARTICIPANTS CXL was performed on 13 patients with mycotic keratitis who presented poor or no response to topical voriconazole treatment. METHODS The clinical features, symptoms, treatment results and complications were recorded retrospectively. The corneal infection was graded according to the depth of infection into the stroma (from grade 1 to grade 3). The visual analogue scale was used to calculate the pain score before and 2 days after surgery. MAIN OUTCOME MEASURES Grade of the corneal infection. RESULTS Mean age of 13 patients (6 female and 7 male) was 42.4 ± 17.7 years (20-74 years). Fungus was demonstrated in culture (eight patients) or cytological examination (five patients). Seven of the 13 patients (54%) were healed with topical voriconazole and CXL adjuvant treatment in 26 ± 10 days (15-40 days). The remaining six patients did not respond to CXL treatment; they initially presented with higher grade ulcers. Pre- and post-operative pain score values were 8 ± 0.8 and 3.5 ± 1, respectively (p < 0.05). CONCLUSIONS The current study suggests that adjunctive CXL treatment is effective in patients with small and superficial mycotic ulcers. These observations require further research by large randomized clinical trials.
