Objectives: To determine the epidemiology and management outcome of preseptal cellulitis seen at a tertiary eye hospital within a period of 13 years. Materials and Methods: The case files of all patients seen with preseptal cellulitis from 2005 to 2017 were reviewed. The information obtained included the patients’ demography, presenting symptoms and signs, research, treatment, outcome, complications and follow-up. Results: Of the 123 patients with preseptal cellulitis reported on the study, 66 were males and 57 females. In a range of 0 to 80 years old, the mean age was 19 years. The commonest predisposing factor was trauma (20.3%) followed by upper respiratory tract infection (11.4%).  Progression to orbital cellulitis was seen in 11.4% of the patients. Conclusion: Preseptal cellulitis is not uncommon in adults as seen in previous studies. Trauma is now more common than sinusitis as a predisposing factor. Despite oral antibiotic therapy some cases may progress to orbital cellulitis.

Objective: To compare the pain relief achieved using sub-Tenon anesthesia with that of sub-conjunctival anesthesia technique in intraocular surgery at the Guinness Eye Centre Onitsha Nigeria. Materials and Methods: Consecutive adult patients who had intraocular surgery under local anesthesia were randomized into having sub-Tenon (3 mL) or sub-conjunctival (0.5 mL) injections using xylocaine ± adrenaline. The manual suture-less surgery technique was used for cataract surgery alone and cataract surgery with pterygium excision; the extra-capsular cataract extraction technique was adopted for combined trabeculectomy and cataract surgery. Surgery duration was recorded. Patient’s pain perception graded as none, mild, moderate or severe. Results: 100 patients made up 51 (51.0%) males and 49 (49.0%) females, age range was 31–88 years, median – 68 years, participated. Sub-Tenon anesthetic technique was used in 52 (52.0%) and sub-conjunctival in 48 (48.0%) participants. Seventy-eight (78.0%) patients had cataract surgery; 10 (10.0%) had trabeculectomy; 7 (7.0%) had combined trabeculectomy and cataract surgery and 5 (5.0%) had pterygium excision with cataract surgery. The mean surgery duration in the sub-Tenon anesthesia group was 31.8 ± 8.5 minutes and 30.2 ± 9.8 minutes in the sub-conjunctival group (P > 0.05). Fifty (96.2%) patients in the sub-Tenon group and 38 (79.2%) in the sub-conjunctival group experienced mild or no pains; 2 (4.2%) patients in the sub-Tenon group and 10 (20.8%) in the sub-conjunctival group experienced moderate to severe pains (P < 0.05). Conclusions: Both sub-conjunctival and sub-Tenon anesthetic achieved effective analgesia in intraocular surgery. But sub-Tenon anesthesia is significantly associated with lower incidence of severe pains.
