Brief Summary

Retinal optical coherence tomography (OCT) is an established technology which enables a detailed cross-sectional visualization of the retinal micro-anatomy, and an objective measurement of its thickness in-vivo. Multifocal electroretinogram (MfERG) measures function of the central retina. Both technologies are relatively new and they provide complimentary to each other information on retinal anatomy and function. The aims of this study is to establish normal ranges for OCT and mfERG measurements related to age, gender and reproductive factors such as parity and the use of contraception in Norwegians; to assess the presumably healthy central retina with the use of anti-inflammatory medication with relation to age and sex ; to study the frequency and extent of retinal thickening and change in retinal function in patients with anterior uveitis not complicated with macular edema; to assess whether the presence of the HLA-B27 haplotype or uveitis recidive affects macular thickening/function in uveitis.

Outcome Measures

Primary Outcomes (1)

  • Macular Thickness Measured With the OCT; in Relation to Age, Sex, Reproductive Factors and the Use of Anti-inflammatory Eye Drops in Health; in Uncomplicated Anterior Uveitis.

    Macular thickness was assessed with the OCT in healthy subjects and in patients with anterior uveitis. Data was analyzed with respect to age, sex, parity, the use of hormonal therapy, after treatment with to types of anti-inflammatory eye drops, and in uncomplicated uveitis.

    Macular thickness measured with the OCT

Study Arms (2)

Diclofenac

EXPERIMENTAL

Preservative- free Diclofenac Na 0.1 % eye drops were applied in one consecutively assigned eye of healthy volunteers four times a day for three days, after which macular thichness was measured in both subjects' eyes with the OCT .

Drug: Diclofenac

Dexamethasone

EXPERIMENTAL

Benzalkonium-reserved Dexamethasone Sodium Phosphate 0.1% was applied in one consecutively assigned eye of healthy volunteers six times a day for three days, after which macular thickness was assessed in both subjects's eyes with the OCT.

Drug: Dexamethasone

Interventions

Preservative- free Diclofenac Na 0.1% eye drops (Voltaren Ophta SDU;Novartis Pharms). One drop four times daily in one eys for three days. The evaluation of macular thickness/function after 3 days use of anti-inflammatory eye drops in healthy subjects is the only sub-study involving an intervention design.

Also known as: Voltaren (Ophta SDU;Novartis Pharms) eye drops.
Diclofenac

Dexamethasone sodium phosphate 0.1% eye drops (Spersadex OmniVision, Novartis Pharma), one drop six times daily for three days in one eye. Pharms). One drop four times daily in one eys for three days. The evaluation of macular thickness/function after 3 days use of anti-inflammatory eye drops in healthy subjects is the only sub-study involving an intervention design.

  • Patients with ocular comorbidity or compliactions to their anterior uveitis, such as elevated ocular pressure or glaucoma.
  • Previous or current macular edema or other posterior segment complications related to uveitis.
  • Subjects with visual acuity worse than 0.8
  • Subjects/patients with cataracts or other ocular media opacities
  • Subjects/patients who are allergic to local anesthesia or mydriatics.
  • Subjects/patients with high myopia/hyperopia
  • Subjects/patients who have had intraocular surgery, although previous uncomplicated LASIK correction for low-grade myopia were accepted.
  • Subjects/patients who cooperate poorly.
